5 Key Takeaways
-
1
Scleral lens fogging may arise from deposits on the anterior surface or particulate accumulation in the post-lens tear reservoir.
-
2
Anterior surface fogging may improve temporarily with blinking or artificial tears and can result from tear film instability, cosmetics, or contaminants.
-
3
Managing anterior surface fogging focuses on the ocular surface, tear supplementation, lens cleaning, and surface wettability.
-
4
Post-lens reservoir fogging appears as material moving within the fluid behind the lens and may cause progressively cloudy vision that blinking does not resolve.
-
5
Post-lens reservoir fogging warrants reassessment of lens fit, including clearance and haptic alignment, to minimize unwanted fluid exchange.
